CAR-COUPLING.

SPECIFICATION forming part of Letters Patent No. 289,985, dated December 11,. 1883.

Application filed July 2,1883.

(Xo model.)

To aZZ whom t may concern:

Be it known that I, DAVID l?. CoRY, of Consecon P. O., in the county of Prince Edward and Dominion of Canada, have invented certain new and useful Improvements in Car- Couplings; and I do hereby declare that the following is a full, clear, andexact description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which forma part of this specification. Y

This invention relates to an improvement in` automatic coupling devices for cars. Its object is to provide an improved constructionin such devices intended to be prompt and cer` tain in action, and adapted to be readily applied to cars as ordinarily constructed.

To these and other ends that will appear the invention consists in the matters hereinafter described, and pointed out in the claims. f

In a car-coupling embodying my invention the draw-head is preferably of the general form of those ordinarily used, having an end opening for the admission of the link and a vertical aperture for the coupling-piu. The draw-bar is connected to the car so as to yield backwardly when the cars are brought together inthe act of coupling, and like those commonly 4in use may be also adapted to draw outward from its normally advanced position when subjected to pulling strain. In the drawhead the portion of the aperture for the'coupj ling-pin above the link-opening is provided with an offset or projection constructed to sup-l port and retain the coupling-pin elevated and in a position with its upper end inclined to the rear, or toward the body of the car, the

aperture for the coupling-pin being otherwise so constructed that when the pin is thrown into a vertical position the lower end thereof pin will descend into position for holding the link. A stationary part, usually a notched projection placedupon the end of the car above and adjacent to the draw-head, is arranged to engage the upper 'end of the coupling-pin when the draw-head is forcedbackward by the forcible contact of the cars in coupling, so that the pin will be thrown into a. vertical position, and thus disengaged from j coupler in operation, and still others relating to the spring-support of the draw-head, will be hereinafter more fully explained.

In the accompanying drawings, Figure l is aside elevation of arcarcoupling constructed in accordance with my invention. Fig. 2 is a verticallongitudinal section of the draw-head. Fig. 3 is a plan View of the same. a section of the drawhead, taken upon line x a: of Fig. l., Fig.' 5 is a section taken upon line y-y of Fig. 1.

' A A are two longitudinal frame-pieces of a car, and A is one of the transverse end timbers thereof.

B is a draw-head upon a draw'bar, B', which, as here shown, is supported by spring-connections, which permit said drawdiead to yield both longitudinally and vertically, as will be hereinafter more fully described. As a preferable construction, the draw-bar B', at its rear end, is provided with a rearwardly-di rected projection, b', fitted to apertures in the plates D', which are supported movably by and between two parallel loop-straps or brackets, d, secured one to each of the frame-pieces A in the position shown. Between the plates D D is interposed a coiled spring, D2, 'and a pin, D, exterior to the rearmost plate, confines said plates and spring in place. By these means the draw bar and head are held in a position from which they are moved backward or forward, according as outward strain or in wardpressure is applied to said bar or head. The draw-bar, near the head, is conned in a fixed loop-strap, C, embracing the bar and depending a few inches below the bar, in the lower portion of which is located a coiled spring, C2, that upholds the bar.V The eX- pansive movement of the spring C2 is limited by a bolt, c', inserted through a plate, C', above'- the spring, and passing downward through the interior of the spring and loosely through the lower horizontal part of the strap C', beneath which it is provided with a nut, c2. The

Fig. 4 is IOC v vplate C is constructed to project both in front andv rear ofthe strap or bracket C, so as to:v

f while the draw-bar slides thereon.

ject of the construction last described is to sus:-y

maintain the spring in an upright vposition The ob- The draw-head Blis'provided with the bell mouthed opening or recess I), for the entrance i of a coupling-link, F, of ordinary construction, and with a vertical .f1pe1ui1e...I B2, for .the

insertion of a con ilinfr-iin E. The walls of o lv s the ajiierturcb" are upwardly extended at the vtop ofthe draw-head, as shown bl, Fig. 2,

, so as to give more than ordinary length to the portion ot' the said aperture above the link-r openingvb. ln the i'ront wall of said upper portion ofthe aperture is formed a recess, b, to allow the pinE to be tiltedv and supported vin the rearwardlyi`nclincd position, (shown in Fig. 2,) with its lower end resting upon the bottomsurface, B, ofthe the saidzre'cess, and

its rear surface resting against the top and rear v edgeI of the apcrturelz.

v l Upon the end piece, A, ofthe car-frame, when having the relative position shown, is ixed a projecting part, u,

y y the frontvedge of which proximates the pin E v 3o when said pin is supported in the rearwardlyinclined positiondescribed, so that when the draw-head vis forced inwardly by contact with the opposing draw-head of another car at the time that the cars como together in the act of being coupledI the bolt will strike vagainst the projection c and will be thrown forward intoa vertical position. In this operation the lower end of the pinis obviously swung olf the supporting projection B, and the pin is allowed to fall through the head and through the link introduced from the adjacent car.

The proj ection a may manifestly be so placed as to furnish the Arear support for the upper end of the pin E, instead of providing such support in the draw-head; but the construction shown is considered preferable for obvious reasons. The front edge of the projection u is notched, as shown at a in Figs. 2, 3, and 5, so as to hold thcuppcr end of the pin from lateral movement, such construction being especially desirable when an ordinary rou-nd pin is used, instead of a pin inthe form shown in the drawings.

The support or rest B, although shown in the drawings as forming the lower wall of a recess, b3, formed in the draw-head, may be` constructed in any other desired or preferred manner. It may, for instance, be a separate cross piece or bar placed in the proper position to hold the end of the pin, as in the case of an open or skeleton draw-head; or it may be constructed to engage a projection upon the edge of the pin instead of its end; or the same result may be obtained by projections upon the side walls of the draw-head openings constructedv to engage lateral projections upon t-he pin.

lhe coupling-pin l vis provided,vas shown in the.drawingsatv its lower end with lateral and are extended into the sides of the recess bi, sous to permit the pinsc to enter said recess when the lower end ofthe coupling-pin is thrown iorward upon the said support.v The pins c described are not essential to the main features of myinvcntion, and other well-known devices may be used to prevent the entire ywithdrawalv of the pin; or vsuch devices may be dis-v pensed with and a loose conpling-pin of the ordinary construction used; or the coupling pin maybe attached by a chain to the carin v vorder to prevent its being lost ormisplacedf. y

For the purpose of supporting alink placed v in. the:draw-l'ieadprevious to coupling ina substantially horizontal position, and so that its projectingr end will be in position to enter an opposite draw-headvwhen two cars come together, the upper wall ofthe link-opening b Y in the drawhead is downwardly and rearsurface of the said: aperture that the inner end of alink placed 1n the aperture willrest against f the top surface thereofand its outer end will l thereby bev supported in va horizontal position.

(Shown in Fig. 2, in which the link is indicated in dotted lines.) rlhe lower wall or iioor of the aperture Z) is also downwardly and rearwardly inclined, as shown at B, Fig. 3, so that the inner end of the link will be i'ree to move downwardly, and thereby permit th e outer end thereof to be lifted so as to entera draw-bar placed at a higher level. In the construction ofthe drawhead described downward movement of the outer end of the coupling-link is provided for by the spring C2, which supports the outer end of the draw-bar in the bracket C.

The spring-connection between the rear end of the draw-bar and the car-frame is, preferably, constructed as shown, in order to permit the said draw-bar to yield longitudinally in both directions, or to allow the draw-head to move toward the car under the impact of the opposite draw-head, as before set forth, and to also allowT the draw-bar to yield outwardly when the couplings are under tension. The rearward or inward movement of the drawhead is, however, alone essential to my invention. rlhe plates D and Dare constructed to IIO IOO

the draw-bar, of a backwardly-yielding drawhead having an opening' for the link and a vertical aperture for the insertion of a couplingpin, said'aperture being provided with an offl set or projection above the link-opening, con structed to support the coupling-pin in a backwardly-inclined position, substantially as dethe forward end of the said draw-bar, substan tially las described.

4. The combination, with the car-frame provided with a supporting-bracket, C, ofthe drawbar B', flexibly supported at its end to the car- 2 5 frame, a sliding plate, C', and a spring, C2, substantially as and for'the purpose set forth.

5. The combination, with the car-frame provided with a supporting-bracket, C, ofthe drawbar B', iiexibly connected at one end to the carfrarne, a sliding plate, C', a rod, c', a nut, c2, and a spring, C, substantially as and for the purpose set forth. p

VIn testimony that I claim the foregoing as my invention I affix my signature in presence of 3 5 two witnesses.
